Accidental injection of hydrogen peroxide into the inferior vena cavaART-2022-127918Contrast cavography during removal of a vena cava filter in pa- tients treated via thrombectomy for pulmonary embolism is a widely performed procedure, which may involve potentially serious com- plications if the human factor fails. Accidental injection of hydrogen peroxide (H2O2) after mistaking it for contrast material can have fatal consequences. We present the case of a patient who was acciden- tally injected with a high quantity of hydrogen peroxide. The prepa- ration of a preoperative checklist, the amount of H202 injected and the operator’s skill in aspirating the substance are decisive factors in avoiding such complications.2022http://zaguan.unizar.es/record/11208910.52768/2766-7820/1599http://zaguan.unizar.es/record/112089oai:zaguan.unizar.es:112089Journal of Clinical Images and Medical Case Reports 3, 1 (2022), 1599-1602by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
